Willpower is all about how powerful you think you are. We have heard the stories in the past like, there were some people who were so powerful that they could do anything.

I like the example you quoted in your article of a baby, you willpower grows as you grow, but it depends on the strength of your mind, Suppose you want to do something, and the other people think that it is impossible, but you know you can do that, it's your willpower, whatever is the task, how tough it is, if you can think you can do that, yes you can do that.
